Study Notes
Disadvantages of Oral Method
- One disadvantage of the oral method of drug administration is that it may not be suitable for certain patients.
Advantages of Subcutaneous Injection
- Subcutaneous injection is advantageous for drug administration because it allows for a slower and more consistent release of the medication.
Disadvantages of Subcutaneous Injection
- The chief disadvantage of subcutaneous injection is that it may cause tissue irritation or inflammation.
Limitations of Oral Method
- Limited use of the oral method is observed in some patients because it may not be effective due to factors such as gastrointestinal disturbances or liver disease.
Subcutaneous Tissue Location
- Subcutaneous tissue is located beneath the skin.
Importance of Aseptic Technique
- Aseptic technique is important for needle injections to prevent infection and ensure the safety of the patient.
Allowing Antiseptic Solution to Dry
- Allowing the antiseptic solution to dry on the skin surface prior to the insertion of the needle helps to prevent bacterial growth and reduce the risk of infection.
Intradermal Injections
- The upper arm area is commonly used for intradermal injections.
Advantages of Intramuscular Injections
- Administering drugs through intramuscular injection is advantageous because it allows for a faster and more consistent absorption of the medication.
Patient Positioning for Gluteal Injections
- The patient should lie on their side with their knees bent for an intramuscular injection to the gluteal muscle.
Palpating the Muscle
- Palpating the muscle before inserting the needle for an intramuscular injection helps to identify the correct location and avoid nerve damage.
Irritating Drugs
- Drugs that are irritating to subcutaneous tissue are often given through intramuscular injection to avoid tissue irritation or inflammation.
Intradermal Injection Angle
- A 1.2 cm (1/2 inch) needle should be inserted at a 10-15° angle for an intradermal injection.
Expelling Air from the Needle
- Expelling air from the needle before injection helps to prevent the injection of air into the tissue, which can cause discomfort and other complications.
